AkzoNobel Industrial Chemicals b.v., Rotterdam.
Safe treatment of wastewater for the Botlek Chemical Park.

The project
The wastewater generated by AkzoNobel's chemical park at Rotterdam Harbour is unusual because of the complex nature of the wastewater resulting from the production of chlor-alkali products, vinyl chlorides and herbicides at the different businesses located on the site. Faced with the prospect of further production challenges in the future and the need for sustainable, state-of-the-art wastewater treatment processes, AkzoNobel decided to look for a competent and expert partner to extend and then manage the facilities on a long-term basis.
 

 

 

The procedure
By implementing an optimization concept, drawn up to fulfil AkzoNobel's individual requirements, the performance of the two-stage facility (chemical/physical precipitation phase and biological treatment) has been able to be increased. Furthermore, the way wastewater is accepted has become more flexible, the amount of chemicals used has been reduced and less sludge is generated. By implementing REMONDIS' accredited plant management concept, AkzoNobel now also has access to the company's know-how gained from running numerous industrial wastewater treatment facilities.
